1 Furthermore. This chapter contains various injunctions, by which he trains up the Thessalonians to a holy life, or confirms them in the exercise of it. They had previously learned what was the rule and method of a pious life: he calls this to their remembrance. As, says he, ye have been taught. Lest, however, he should seem to take away from them what he had previously assigned them, he does not simply exhort them to walk in such a manner, but to abound more and more. When, therefore, he urges them to make progress, he intimates that they are already in the way. The sum is this, that they should be more especially careful to make progress in the doctrine which they had received, and this Paul places in contrast with frivolous and vain pursuits, in which we see that a good part of the world very generally busy themselves, so that profitable and holy meditation as to the due regulation of life scarcely obtains a place, even the most inferior. Paul, accordingly, reminds them in what manner they had been instructed, and bids them aim at this with their whole might. Now, there is a law that is here enjoined upon us — that, forgetting the things that are behind, we always aim at farther progress, (Philippians 3:13) and pastors ought also to make this their endeavor. Now, as to his beseeching, when he might rightfully enjoin — it is a token of humanity and modesty which pastors ought to imitate, that they may, if possible, allure people to kindness, rather than violently compel them. ⁵⁶⁶⁵⁶⁶     “Que de les contraindre rudement et d’vne façon violente;” — “Rather than constrain them rudely and in a violent manner.”

3 For this is the will of God. This is doctrine of a general nature, from which, as from a fountain, he immediately deduces special admonitions. When he says that this is the will of God, he means that we have been called by God with this design. “For this end ye are Christians — this the gospel aims at — that ye may sanctify yourselves to God.” The meaning of the term sanctification we have already explained elsewhere in repeated instances — that renouncing the world, and clearing ourselves from the pollutions of the flesh, we offer ourselves to God as if in sacrifice, for nothing can with propriety be offered to Him, but what is pure and holy.

That ye abstain. This is one injunction, which he derives from the fountain of which he had immediately before made mention; for nothing is more opposed to holiness than the defilement of fornication, which pollutes the whole man. On this account he assigns the lust of concupiscence to the Gentiles, who know not God. “Where the knowledge of God reigns, lusts must be subdued.”

By the lust of concupiscence, he means all base lusts of the flesh, but, at the same time, by this manner of expression, he brands with dishonor all desires that allure us to pleasure and carnal delights, as in Romans 13:14, he bids us have no care for the flesh in respect of the lust thereof. For when men give indulgence to their appetites, there are no bounds to lasciviousness. ⁵⁶⁷⁵⁶⁷     “Il n’y a mesure ne fin de desbauchement et dissolution;” — “There is no measure or end of debauchery and wantonness.” Hence the only means of maintaining temperance is to bridle all lusts.

As for the expression, that every one of you may know to possess his vessel, some explain it as referring to a wife, ⁵⁶⁸⁵⁶⁸     “Au regard du mari;” — “In relation to her husband.” as though it had been said, “Let husbands dwell with their wives in all chastity.” As, however, he addresses husbands and wives indiscriminately, there can be no doubt that he employs the term vessel to mean body. For every one has his body as a house, as it were, in which he dwells. He would, therefore, have us keep our body pure from all uncleanness.

And honor, that is, honorably, for the man that prostitutes his body to fornication, covers it with infamy and disgrace.
